This repository contains supporting data for: "Global sustainable irrigation expansion potential in a 3ºC warmer climate" Email: lorenzo_rosa@berkeley.edu The dataset contains: -Annual irrigation water requirements (IWR) under baseline and 3C warmer climate. Units: 10^9 m3. -Extent of rain-fed croplands not exposed to green water scarcity (GWS) under baseline and 3C warmer climate, as in figure 1 in the paper. -Extent of sustainable irrigation expansion potential with soft-path, soft-path and deficit irrigation, and hard-path approaches under baseline and 3C warmer climate, as in figure 2 in the paper. Files are uploaded in netcdf formats.
